Click this to see how intellisense displays variables in your code that have the prefix you typed.

Many programmers use the Reddick's naming conventions ( http://www.xoc.net/standards/rvbanc.asp )
or a shorter version you developed yourself. Code VBA supports Reddick as a default, but lets you customize it to fit your needs.

Support of the naming conventions consists of automatically adding the appropriate prefix (optional).
Considering the number of classes that may be used - 300+ in Excel -, not every type has a prefix defined.
We implemented an algorithm that proposes a prefix in case it is not present in the prefixes file. If you don't like it, add a better one to the file.e.

To change or add prefixes open the file that contains the prefixes:

Alt-CPC | Menu: Code VBA » Preferences » Change prefixes

the prefixes are stored in a file called prefix.txt. Below you see a bit of it's content.
